Publisher's Page

More than ever before, there is widespread interest in studying bumble bees and the critical role they play in our ecosystems. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Richly illustrated with color photographs, diagrams, range maps, and graphs of seasonal activity patterns, this guide allows amateur and professional naturalists to identify all 46 bumble bee species found north of Mexico and to understand their ecology and changing geographic distributions.

Patterns of widespread decline in North American bumble bees.
By Cameron et al.
Proc. Natl. Acad. Sci. 108: 662-667. , 2011
Full Text

Cameron et al. (2011) quantified dramatic range-wide population declines in B. occidentalis, B. pensylvanicus, B. affinis, and B. terricola that have occurred over the last few decades.

Abstract (part):

Here, we report results of a 3-y interdisciplinary study of changing distributions, population genetic structure, and levels of pathogen infection in bumble bee populations across the United States. We compare current and historical distributions of eight species, compiling a database of >73,000 museum records for comparison with data from intensive nationwide surveys of >16,000 specimens. We show that the relative abundances of four species have declined by up to 96% and that their surveyed geographic ranges have contracted by 23–87%, some within the last 20 y.

Bumble bees (Hymenoptera: Apidae) of Texas: historical distributions.

Abstract: I compiled data from several museum collections to map historical distributions of species of bumble bees across Texas. Bombus auricomus, B. bimaculatus, B. fervidus, B. fraternus, B. griseocollis, B. impatiens, B. pensylvanicus, B. sonorus, and B. variabilis were confirmed from the state based on vouchered specimens.

As currently understood, the bumble bee fauna of Texas consists of nine documented species.

Bumble Bees of the Western United States
By Jonathan Koch, James Strange, and Paul Williams
U.S. Forest Service and the Pollinator Partnership
Scroll down to the 3rd item on this web page... to find links for either downloading the free PDF of "Bumble Bees of the Western United States", or for ordering a (color) hard-copy of the work from the "Pollinator Partnership" for $15.

This is a nice compact guide to western bumble bees. Includes discussion, photos, numerous dorsal-view color diagrams (illustrating variation), host plants, etc. for each of the 30 species covered. Also includes general discussion of bumble bee biology at the beginning of the text, and a key to species (for females only) at the end of the book.
